Relaxation is one of the elemental forces that keeps human bodies alive, alongside air, water, fire, and anti-fire. Ease into your element with today's Groupon: for $50, you get $100 worth of services at Kasia's European Day Spa in Manhattan.

Kasia's dedicated staff executes services for the face, body, and nails with a keen eye and a bevy of high-end products. The 45-minute organic pumpkin peel gently wipes away B-list layers of skin, minimizing discoloration, sequin deposits, wrinkles, and blemishes ($100). A full leg and bikini wax prepares bodies for bathing suits ($70), while a full Brazilian wax prepares bodies for haute-couture birthday suits ($65). Add a dash of color to digits with an organic full manicure, which coddles keratin without enlarging carbon paw prints ($40).

Saunter into the centrally located spa (closed Sundays) to experience a slack-jawed state of relaxation. Kasia's asks clients to silence cell phones upon entry in order to minimize stressful distractions and adolescent ringtone preferences.

Reviews

Kasia's European Day Spa has been featured in Beauty News NYC, and six Citysearchers give it an average of four stars:

• From the moment you walk into this cute, cool, space, with its exposed brick and pale green walls, and sit on the comfortable window seat cushions for a brief wait, you instantly feel relaxed. – Beauty News NYC
• I spent over eleven years in Manhattan trying to find the best day spa...and unfortunately only found it about two years before I left for San Francisco - Kasia's! I'm lucky enough to continue to travel to NYC on a regular basis, and the first thing I do is book some time with Kasia. – kcdubya, Citysearch, 7/28/08
